Safety measures during installation

Observe the following safety notes when performing the work described in Section Installation.
Danger
Risk of death by electrocution!
• Only technical professionals may perform the work described in Section Installation.
• Always disconnect all DC and AC cables as follows before starting work on the inverter:
1. Turn the AC circuit breaker to off. Take measures to prevent the system from being uninten-
tionally switched on again.
2. Set the DC circuit breaker on the inverter to position 0. Take measures to prevent the system
from being unintentionally switched on again.
3. Disconnect the Multi-Contact MC4 connections of the DC cables according to the manufac-
turer's instructions. A special tool is required for this.
Warning: DC cables carry voltage when the solar modules are subjected to sunlight.
4. Pull out the AC plug from the inverter as described in Section 8.10, p. 66.
5. Check that all pins of the AC plug are free of voltage. Use a suitable voltmeter for this (do not
use a simple neon phase checker).
• Do not connect cables to the inverter until explicitly asked to do so in the instructions.
• Do not open the casing. Risk of death. Invalidation of the guarantee.
• Connect only suitable circuits to the RJ45 sockets (RS485 interface).
• Lay the cables such that the connection cannot come loose accidentally.
• When laying cables, ensure that no damage occurs to any of the constructional fire safety meas-
ures in the building.
• Make sure that no inflammable gases are present.
• Observe all applicable installation regulations and standards, national laws and connection values
specified by the regional power supply company.
Notice
Danger of damage to the inverter or power reduction (derating)!
• The mounting location must satisfy the following conditions:
– The mounting location and immediate environment are permanently fixed, vertical, flat, non-
inflammable and not subject to constant vibration.
– The permissible ambient conditions are conformed to; see Technical data Inverter, p. 76.
– The following free spaces must be present around the inverter:
At the sides 150 mm
Above/below 250 mm
• Do not install the inverter in areas where animals are kept.
• Install the inverter in an environment that is as free as possible from dust to avoid impairment of
the cooling function.
• Observe the connection ratings specified on the inverter type plate.
• The DC cables must not be connected to an earth potential (DC inputs and AC output are not
galvanically isolated).
• Do not install inverters directly above each other, but rather offset so that the upper inverter is
not heated by the radiated heat of the lower inverter.
Note
• Avoid exposing the inverter to direct sunlight.
• The display must be readable on the installed device.
• Choose an installation location where the noise emission of the device will not be a disturbance.
